PIVlab uses uipickfiles.m to load the paths and filenames of image data. You could replace this function with a custom function that loads matrices from the Matlab workspace. See the documentation of uipickfiles.m to understand it's data structure.
thanks for your great programm.
What I would like to know:
Is it possible to import the images (matrices) directly from the current Matlab-session without saving them to file?
